WIRELESS BECEPTACLE.

Patented Jan. 15, 1918.

Application filed July 24, 1913. Serial No. 780,985.

To all whom it may concern:

v Be it known that I, HENRY T. Pals'rn, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Wireless Rece ta clesfof which the following is a speci cation.

One object of m invention is to provide a novel form of lamp or plu receptacle which in addition to being of re ativel simple and substantial construction, shal have the connections between its various terminals made of permanently mounted strip metal pieces to the exclusion of wires.

I also desire to provides. receptacle, whose contact members and terminals I shall be identical in construction, and so arranged that the structure as a whole is bi-later'ally symmetrical.

Another object of the invention is to provide a receptacle having a contact carryin member. provided with terminals for attac ment to a pair of current sup ly mains or conductors and of such design t at it may be used in connection with any of several difierent forms of receptacle bodies, the construction being such that said contact carrying member may be conveniently adapted to receive either a contact plug or a lamp.

These objects and other advantageous ends I secure as hereinafterset forth, reference bein had to the accompanying drawing sfinw ich:--

igures 1 and 2 are respectively a side elevation and a plan of a portion of a conduitillustrating one form of my invention applied thereto;

ig. 3 is a l-inverted perspective of one form of receptacle member forming part of my invention; a Fig. 4 ,is a pers ective view-of the con- Fi 5 is an inverted perspective view of an a apter member which may be used with the contact carrying member shown .in

Figifi is a longitudinal sectionon the line M Fig. 2:

Fig. 7 is a transverse section of the receptacle member shown in .Figs. 1, 2 and 3;

Fig. 8 is a transverse section of a conduit illustrating the contact carrying and adapter members mounted thereon;

' the opening are Fig. 9 is a side elevation partly in section of the adapter and contact carrying mem- In the above drawings. 1 represents a ortion of a metalconduit which has the orm of a tubular structure internally threaded at its ends as indicated at 2 in Fig. 6, for the rece tion of the correspondingly threaded en s of metallic pipes designed to carry electrical conductors. One sideof this conduit is provided with. an elongated rectangular opening designed to receive a contact carrying member 3, (Figs. 4 and 10), it being noted that the facial edges of lane and designed to recelve the plane e ges of the adapter or receptacle members 4 and 5, as may be desired. The contact carr ing member 3 con-- sists of a casting of insu ating material havmg a body art 6 substantially rectan lar in lan as s own in Fig. 10 and longitudinal y elongated ends 7 so that when intro-. duced into the" conduit 1, as shown in Fig. 6, 1t with said ends forms in effect, a longltudinal partition therein, which receives a' pair 0 current conductors on its opposite sides. a

On each of these ends 7 is a head '8 overhung jectmg flanges of the opening in the con-- duit 1 and-notched at 9 to permit of the.

so as to rest upon the inwardly pro- 1 passage of a holding screw 10. Between the somewhat less than 180, the arrangement being such that their main or body portions extend immediately adjacent the vertical ends of the recess between the heads 8 with their free, bent over ends projecting toward each other.

The upper face of the body 6 is divided into two similar parts by a diagonal rib 1 or partition 14 and onopposite sides of this are mounted terminal pieces 15 and 16 each having a holding screw 17. The outer extremity of each of said terminal pieces 1s bent or curved parallel toand adjacent one side of the head of its screw so as to. confine thereunder, the wire constituting the electrical conductor'which extends through ,a the'conduit 1. Asshown in Figs. 4 and 8, the opposite sides of the body 6 have their top portions somewhat concaved for the reception of these extremitiesof the terminal pieces and for the receptlon and support of the current conductm wires or .mains which as before indicate run over. said body portions along opposite sides of the ends 7 The terminal piece is'electrically connected tothe contact piece 12 by a screw 18 extending upwardly through the body 6 of the contact carrying member 3 and having its head counter-sunk in a suitable cavity in the underside thereof. Similarly the terminal piece 16 is electrically con:

\ nectedto the contact piece 11 by a second a 8 of the body of the contact carryingmemconduit, -1-. to which it is held "10f T he upper face of this member-has a.

screw l9.v It is noted that the two contact membersll and 12 have their to s substantially flush with the top faces 0 the heads her and their adjacent faces are each provided with a pressed out pro ection or lug for a purpose hereafter noted.

If it should bedesired to use a lamp or attachment plug receptacle inconnection with the conduit and contact carryin mem-,

her, I may employ a'combination 0 parts such asis illustrated in Figs. 3 and 7. Such a. member 5 preferably consists of a hollow substantially rectangular base 21 designed to fit, upon the face of the'opening in the y the screws cylindrical extension 22in which is mounted -athreaded metallic shell 23 forming one of the terminals of the receptacle. As shown in Fig. 7, said shell is provided at its inner end with inwardly projecting portions 24 electrically connected by screws 25 with a curved metallic plate 26 set in a suitable re- I so '- member.

' cessin the under face of a transverse partition 27 formed integral with and extending across-{the hollow base 21of the receptacle This plate 26 has an integral extension 28 lying at right angles to its plane against one face of the partition 27, there being a cavi-r tension, designed .00 re ive the ofone of the contact pieces 11 ing to the'contact member.

The opposite vertical 'side of the partition 27- has a contact plate 30 whose lower end 31 projection 20 or 12 belongcontact plug,

r depression 29 in this ex-.

. one end a hole for the reception of the screw 33 and bent at its middle point through an angle of substantially 180, so that its free end extends over its opposite end as shown .in Fig. 6, although spaced away from the same.

The plate 30 has a. depression or recess (Fig. 6) for the reception of one of the pro ections 20 of the spring contact 12, for example and under conditions of use the receptac e member would be mounted on the conduit 1 with its partition 27 extending between the two pontact-members 11 and 120i the contact carr ,ing member,,-so that said contacts would e'ectrically enga e the parts 28 and 30, and would thus be -1n electrical connection with the shell 23 and the central contact 32. As shown in Fig. 6 thescrews 10 rigidly and removably connect the con tact carrying member to the oonduit.

Should it be desiredto utilize the contact carrying member,-with or without the conduit, for the reception of a contact plug34, Fig.- 8, the receptacle member would be replaced by. the adapter member shown in Fig. 5. This latter consists ofa hollow, substantially rectangular base piece 21, which instead of the cylindrical extension 22, has a plane upper face with a central rectangular perforation 35 The interior of this base is similar to that of the receptacle member except that its end partition27 is omitted to permit of the passage of a central projection 36 from the insulating body 34 of the which on two of lts opposite faces is provided with a pair of contact plates 37 and 38. The dimensions of this projection 36 an of said plates are such that when the adapter member 4 is mounted over the-contact carryiiig member 3, the heads 8 of-the latter fit within the recesses 39 and 402a the ends of said adapter member and the contact plates 37 and 38 of the contact plug 34 fit between and electrically engage the spring contacts 11 and 12, with the projections .20 of said contacts fitting into the openings 41 of said plates, as described and claimed in my application for patent on .an attachment plug, filed of even date herewith, Serial Number 780,986. The contact plates 37 and 38 are electricall connected to the two conductors plug 34.

Undenoper" ymg conditions a pair of ourrent'carrying conductors in the conduit 1 extend on opposite sides of the relatively of a cab e 42 which enters the contact narrow body of the contact carrying memres ectively and thence to the terminals 23,

an 32 of the receptacle member or to the contact plates 37 and 38 of the contact plug 34 as the case may be.

In that form of my invention shown in Figs. 11 to 14 inclusive, I have illustrated the contact carrying member as adapted to fit into a wall box or cabinet, and for the purpose of attaching it to the coverplate of such structure, it is provided with a pair of perforated. metal lugs or plates 43 at its opposite ends. In this instance as before, its body is formed of a casting 3 having heads 8 between which is'a recess'for the reception of two similar spring contacts 1 1 and 12". In this instance, however, said contacts are integral with the terminal plates 15 and 16 which lie in recesses at the opposite sides of the body 6*. and ad acent vertically extending channels 45 through which conductors may be extended for engagement with the holding screws 17 This form of receptacle is particularly adapted for main connection witha contact plug such as is shown in Figs. 8 and 9 and for the purpose of adapting it to this device, I provide a substantially cyhndrr' cal casting 46 shaped to fit between the heads 8 of the contact carrying member and of such length as to be substantially flush with their top faces. This casting is provided with a central passa e of'substantially rectangular section esigned to receive. the projection 36 with the contact plates 37' and 38 ofthe contact plug 34, so that when said casting is in place as illustrated in Fig. 11, the said contact. plates electrically engage the twospring contacts 11" and 12.

In any case it will be noted that the receptacle is ofa relatively simple construction and while being designed for engagement with the main current carryin conductors of the circuit, employs strips or spring bars throughout for transmitting the current between its terminals. It will moreover he noted that the device, in addition to being-simple, is substantial-and has its parts so arran ed that the danger of short circuiting is re need to a minimum.

I claim a 1. A wireless receptacle eonsistin of an insulating casting including a re atively narrow body having upwardly extending and portions spaced apart to .form a recess and including. lateral extensions; with two conducting members of similar construction consisting of U-shaped spring contactportions in the recess respectively adjacent end portions of the casting and laterally projecting terminal portions on the outside surface of the body extensions for the attachment of conductors.

2. A wireless receptacle consistin of a relatively narrow insulating casting aving two upwardly projecting ends spaced apart to iorm a recess; a rib extending diagonally across said recess; and two similar conducting members having contact portions respectively mounted in opposite portions of the recess on opposite sides of the rib and provided with terminal portions projecting respectively on opposite sides of said castmg.

3. A wireless receptacle consisting of an elongated insulating body having upwardly projecting headed end portions spaced apart to form a recess and provided with lateral extensions between and below the top surfaces of said end portions; with two similar conducting members having spring contacts respectivelymounted in opposite parts of the recess adjacent the ends of the body and also provided with laterally projecting terminal portions respectively projecting over the side extensions of the casting, the body being cut away on each side under said end portions to provide channels leading to the terminal portions.

4. The combination ofia conduit for electric conductors having a side opening; with a'receptacle mounted in the opening so as to extend into the conduit, said receptacle consisting of a relatively narrow body longitudinally dividing the conduit into two parts; and'conducting members mounted on said body including oppositely disposed contact portions lying in two parallel. planes and terminal portions respectively mounted within the two parts of the conduit.

5. The combination of a conduit for electric conductorshaving aside, opening; a receptacle mounted in said opening and includin'g a relatively narrow body extending into the conduit so as to divide it longitudinally into two chambers, there being lateral projections extending from opposite sides of the body into said chambers; two con ducting members having contact portions respectively opposite each other; and terminal portions projecting laterally upon the lateralextensions of the'body within the two chambers of the conduit.

6. The combination of a conduit for elece duit; with conducting members of similar construction having spring contacts respectively mounted in opposite portions of the recess of the body; and terminal portions extending over the lateral projections of the body respectively within the chambers in the conduit.

7. The combination of an insulatin body; two oppositely disposed contacts t ereon; terminal portions for the contacts respectively extending at opposite sides of the body; and a member consisting of an insulating base having a hollow cylindrical projection; two oppositely disposed contact plates mounted on the bas in positions to respectively engage said contacts; and terminal members in said cylindrical extension respectively connected to said contact plates.

8. The combination of a conduit for electrical conductors having a side opening; a member mounted over said opening and consisting of an insulating base having a hollow cylindrical extension; terminals in said hol- .contact plates of the insulating base; with terminal pieces respectively connected to said spring contacts and projecting on opposite sides of the body within the conduit.

In testimony whereof, I have signed my name to this specification, in the presence of two subscribing witnesses.
